UNITED STATES PATENT TQ RUSSEL P. GORDON, OF LAKEVISTA, COLORADO.

sLme-rnrr.

To all whom it may concern:

Be it known that I, RUSSEL P. GORDON, a citizen of the United States, residing at Lakevista, in the county of Montezuma and State of Colorado, have invented certain new and usefulv Improvements in Sling Trips, of which the following is a specification.

This invention relates to improvements in hoisting apparatus, and more particularly to a tripping device for use in connection with a rope or chain utilized for hoisting hay or like material.

' he main object of the invention is to provide a device of this character, termed in the art a sling trip which is so constructed as to reliably release the ropes by which the load is held avoiding all possibility of a failure to deposit the load at the desired point.

Another object is to so construct a device of this character that it may be tripped from any direction without necessitating the use of a pulley.

Still another object is to provide a device of this'character which is simple and strong in construction and may be cheaply manufactured and readily applied.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made Within the scope of what is claimed Without departing from the spirit of the invention.

, In the embodiment illustrated, the trip constituting this invention comprises a body 1 preferably made of metal cast in one piece. A latch 2 is pivoted at one end to' the lower end of said body 1, said body being bifurcated to provide bearings fora journal for said latch, the furcations 3 of which are beveled on their outer faces. This latch 2.is shown in theform of a heavy bar having a substantially right-angular arm 4 at one end which is bent to form a bearing 5 which is journaled on a pintle 6 mounted in the furcations 3 of the body member. The free end ofthis latch 2 is offset inwardly as shown at '5 and is provided with a longitudinally eX- the body member 1 and which extends through an opening 9 formed in said member as is shown clearly in Figs. 1, 2, 3 and 5. This latch 2 which is designed to support the load carrying rope R, is held in closed position by a catch 10 which is substantially U-shaped in form, one leg thereof being longer than the other and the short leg 11 provided with a laterally offset apertured terminal 11' which is pivotally mounted in a recess 30 formed at the rear of the body 1 as is shown clearly in Figs. 2 and 5. The long arm 13 of this catch member 10 has an obliquely disposed laterally projecting wing 14 provided at its terminal with an aperture 15 designed to receive a knot K formed in one end of the trip rope TR. I The cross bar of the catch member 10 has a lateral projection or 111g 16 against which bears one end of a spring 17, the other end of which is arranged in the form of a coil 18 mounted on a laterally extending core or stud 19 carried by the body member 1 adj acent its bifurcated end, the terminal of said coiled end being wrapped around said body member in the form of a hook as shown at 20 whereby said spring is reliably secured to The body member 1 is provided on its front face with a stop 21 which is designed to be engaged with a shoulder 22 formed on the long arm of the catch member 10 so as to limit the closing movement of said member as is shown clearly in Fig. 1.

This long arm 13 spans the upper portion of the opening 9 of the body member when in closed position and is designed to close behind the nose 8 of the latch 2 as shown clearly in Fig. 5, whereby said latch 2 is securely held in locked position, the catch 10 operating in a plane at right angles to that of the latch 2 so that it will be seen that when catch 10 is moved into open position, latch 2 will be released and will open outwardly and drop downwardly owing to the weight of the load which it supports.

The body member 1 is provided at the end opposite its bifurcated end with a pa1r of transversely alined eyes 23 through which a cable 2% is designed to be threaded for supporting the slip trip on a carriage 25 which is designed to travel on a cable 26 as is shown clearly in Fig. 1. This carriage 25 is of ordinary construction and forms no part of the present invention, hence it will not be described further in detail.

Arranged at the base of the eyes 23 between them and the opening 9 in the body member 1 is a transversely extending trough 27 having a loop 28 arranged at one end thereof and through which the trip rope TB is designed to pass. This loop 28 is arranged substantially in longitudinal aline ment with the trough and has an enlarged lip 29 at its inner side against which the trip rope TB is designed to bear when a pull is exerted thereon from the rear. By so constructing this trough and loop 28 it will be obvious that the catch 10 may be opened by said trip rope TR by a pull exerted from any direction without necessitating the use of a pulley for directing the course of the rope.

The body member 1 has an outstruck portion on its front face forming a longitudinal recess 30 in the inner or rear wall of its rear face in which is formed the aperture 9 through which the latch or tongue 2 extends and another aperture 9 is arranged therein below aperture 9. These apertures are separated by a cross bar 31, one end of which has a shoulder 32 on its outer face which forms a stop to assist in limiting the closing movement of catch 10, the cross bar of said catch engaging said shoulder when the catch is in closed position (see Fig. 3).

The laterally oli'set terminal 11' of the short arm 11 of catch 10 is pivotally mounted in recess 30 adjacent aperture 9 and said arm beyond said offset portion extends through said aperture thereby positioning the catch on the front face of the body 1.

A shoulder 12 is formed on the outer face of the front face of arm 11 at the inner end of its offset terminal 11 and engages one side edge of aperture 9 when-the catch 10 is closed (see Fig. 3).

A rib 83 projects from one side of the aperture 9 as shown in Fig. 2 to form a guide for latch 2 in its closing movement and also to reinforce the body at this point. This rib is beveled on its inner face to facilitate the closing of latch 2.

In the operation of this improved trip device, the rope R having been engaged with the object to be hoisted, upward movement is produced by drawing on the end 2 1- of rope 24 which passes over suitable pulleys P on the carriage 25 and is threaded through the eyes 23 in the trip device as is shown clearly in Fig. 1. Afterthis device carrying the article to be hoisted has been raised to the desired point, the carriage 25 may be drawn along cable 26 by pulling on the rope 25' which is connected with the carriage and after the object has been drawn to the desired location, it may be released and deposited by a pull exerted on the trip rope TR, whereby the catch 10 is disengaged from the nose 8 of latch 2 and said latch under the weight of the suspended object will drop downwardly into the dotted line position shown in Figs. 3 and/1, thereby discharging the object and rendering the device ready for another operation.

From the above description it will be obvious that the releasing of latch 2 by the pull exerted on catch '10 will insure the opening of said latch owing to the weight exerted beyond the pivotal point thereof, said weight being carried at thejunctionof the long and short arms of said latch.

From the foregoing description, taken in connection with the accompanying draw-- ings, the advantages of theconstruction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

I claim:

A device of the class described comprising a substantially rectangular body member with an aperture therein intermediate of its ends with a cross bar dividing said aperture, said bar being offset, asubstantially U-shaped catch having the terminal of one leg offset and pivoted to said body adjacent one side of said aperture, the other leg of said catch which is located at the otherside-of the bar and spaced therefrom being movable across said aperture, a spring In testimony whereof I aflix my signature for holding said catch in closed position, in presence of two witnesses.

and a load carrying latch pivoted on said RUSSEL P. GORDON. member with its free end adapted to be en- Witnesses:

5 gaged by said catch and locked thereby in W. F. Mowmr, closed position. P. J. Sm'rH.
